Update the default NGC image to the April 2023 version.
Found that the docker-compose.yaml variables for month were not being read for the NGC image.
Also found that pip could not be made to always leave pre-installed packages as-is and throw an error when incompatible packages are found.
Also removed the redundant pytest requirement.
